You might not think about it often, but the graphics processing unit inside your computer works harder than almost any other component. It renders every pixel you see, from the Windows desktop to the most demanding video game. For many users, the GPU is also the single most expensive part of their entire system. Given its complexity and the stress it endures, failure is always a possibility. Sometimes a GPU dies without any warning at all. In other cases, your computer sends out distress signals beforehand.
1. Strange Visual Glitches Appear on Your Screen
Perhaps the most unmistakable warning that something is wrong is when you start seeing things on your monitor that should not be there. These are commonly called graphical artifacts. They can take many forms, and they almost always point to a hardware problem deep inside the GPU.
What Do These Artifacts Look Like?
You might notice random blocks of color scattered across the screen. Thin lines, either horizontal or vertical, can flicker in and out of view. Textures in games might shimmer or flash in odd ways. Some users report a checkerboard pattern that covers part of the display. Screen tearing, where the image looks split horizontally, is common in video games, but if you see it on your desktop or in a web browser, that is a red flag. Even user interface elements like menu text or icons can become corrupted and unreadable.
Why Does This Happen?
The GPU chip itself, or the video memory (VRAM) attached to it, is usually the culprit. These components store and process the data that becomes the image on your screen. When a tiny section of the GPU chip fails, or when a memory module becomes unstable, the data gets corrupted. That corruption shows up as those strange visual errors. It is a direct sign that the hardware is struggling to function correctly.
Can You Fix It?
Seeing artifacts is almost always a hardware issue. Software fixes rarely work here. However, there are a couple of things you can try. First, reseat the graphics card in its slot. Turn off your computer, unplug it, and carefully remove the GPU. Then put it back firmly. This ensures a good connection. Second, check the GPU temperature using a free tool like HWMonitor. If the card is overheating, cleaning the dust from its fans and heatsink might help. If the artifacts persist, the hardware damage is likely permanent.
2. Your Games and Applications Crash Under Load
Another common gpu failure signs involves software instability. Your computer might work perfectly fine for browsing the web, checking email, or watching a movie. The moment you launch a demanding video game or start rendering a video, everything falls apart.
What Kind of Crashes Should You Expect?
The application might simply close without any error message. You could see a pop-up that says “Display driver stopped responding and has recovered.” In more severe cases, the entire screen goes black, and you have to force a restart by holding the power button. Your computer might even reboot itself unexpectedly.
Is It Always the GPU?
Not necessarily. A failing power supply can cause crashes under load because the GPU demands more power when it works hard. Unstable system RAM can also produce similar symptoms. A corrupt or outdated display driver is another possibility. The key clue is the timing. If the problem only happens when the GPU is under heavy stress, the graphics card becomes a prime suspect. You can test this by running a stress tool like FurMark for a few minutes. If the system crashes quickly, the GPU is likely the issue.
Steps to Narrow It Down
Start by using a tool like Display Driver Uninstaller (DDU) to completely remove your current graphics drivers. Then install the latest driver from the GPU manufacturer’s website. If the crashes stop, you were dealing with a software problem. If they continue, move on to testing the power supply. A multimeter or a dedicated PSU tester can help, but swapping in a known-good power supply is the most reliable method. If the crashes persist with a good PSU and fresh drivers, the GPU hardware itself is failing.
3. Constant Overheating and Plummeting Performance
Modern graphics cards are designed to run hot. They push themselves right to the edge of their thermal limits to deliver maximum performance. There is a big difference, however, between running at the safe maximum temperature and constantly overheating.
How Hot Is Too Hot?
Every GPU model has a different safe operating temperature. You can look up the specific number for your card online. As a general rule, many NVIDIA cards begin to throttle around 83 degrees Celsius (181 degrees Fahrenheit). Many AMD cards have a higher threshold, often near 95 degrees Celsius (203 degrees Fahrenheit). If your GPU regularly exceeds these numbers, you have a cooling problem.
The Performance Hit
When a GPU gets too hot, it automatically reduces its clock speeds to cool down. This is called thermal throttling. You will notice this as a sudden and dramatic drop in frame rates. Games that once ran smoothly become choppy and laggy. If your card used to hit its maximum boost clock but no longer does, that is a strong indicator that something has changed with its cooling or power delivery.
What Can You Do About Overheating?
The first step is cleaning. Dust is the enemy of cooling. Open your computer case and use compressed air to blow out the dust from the GPU’s fans and heatsink. Ensure your case has good airflow. If cleaning does not help, the thermal paste between the GPU chip and its cooler may have dried out. Replacing the thermal paste is a more advanced repair, but it can restore normal temperatures. If the fans on the GPU have stopped spinning entirely, the card needs a fan replacement or a new cooler.
4. Frequent Blue Screen of Death (BSoD) Errors
A crashing game is one thing. A Blue Screen of Death is something else entirely. While an application crash can be a sign of a GPU issue, a BSoD is much more indicative of a serious hardware problem. Windows has changed the look of the BSoD over the years, but the meaning remains the same: the operating system encountered a fatal error it could not recover from.
Common BSoD Error Codes Related to GPUs
Some error codes are more specific to graphics hardware than others. You might see codes like VIDEO_TDR_FAILURE, VIDEO_SCHEDULER_INTERNAL_ERROR, or PAGE_FAULT_IN_NONPAGED_AREA. These often point to the GPU or its driver as the source of the crash. If you see these codes repeatedly, especially when gaming or using graphics-intensive software, the GPU is a likely candidate.
How to Confirm the Cause
You can use a tool like BlueScreenView to analyze the crash dump files Windows creates. This tool shows you which driver or file caused the crash. If it consistently points to the GPU driver (like nvlddmkm.sys for NVIDIA or atikmpag.sys for AMD), the hardware is suspect. Again, rule out the driver first by doing a clean reinstall. If the BSoDs continue, the GPU hardware is almost certainly failing.
5. Unusual Noises Coming From the Computer
Not all gpu failure signs are visual. Your ears can also alert you to trouble. A healthy GPU should be nearly silent, aside from the sound of air moving through its fans. If you start hearing new or strange noises, pay attention.

What Kind of Noises Indicate a Problem?
A grinding or scraping sound is a bad sign. It often means a fan bearing is failing. The fan might wobble or catch on something inside the card. A loud clicking noise can also indicate a fan issue. In some rare cases, you might hear a high-pitched whine or coil whine. While coil whine is usually not a sign of imminent failure, it can indicate that the GPU’s power delivery components are under stress.
What to Do About Noisy Fans
If a fan is making noise, it is likely on its way out. A failing fan will eventually stop spinning, which leads to overheating and throttling. You can try to clean the fan with compressed air. Sometimes a piece of dust or a small cable is causing the noise. If cleaning does not work, the fan needs replacement. On some high-end GPUs, you can replace individual fans. On others, you might need to replace the entire cooler assembly.
6. The GPU Is Not Detected by the System
This is often a late-stage symptom, but it is one of the clearest gpu failure signs you can encounter. You turn on your computer, but your monitor stays black. Or Windows boots up, but it uses the basic Microsoft display driver instead of your dedicated GPU. Device Manager might show a yellow exclamation mark next to the GPU entry, or it might not show the GPU at all.
Why Does This Happen?
A complete failure of the GPU chip itself can cause the computer to not recognize it. A problem with the PCIe slot on the motherboard can also cause this. The GPU’s BIOS (the firmware on the card) can become corrupted. In some cases, a power supply that cannot deliver enough power to the card will cause it to fail to initialize.
Troubleshooting a Missing GPU
Start with the basics. Reseat the GPU in its slot. Check that all power cables from the power supply are firmly connected to the card. Try the GPU in a different PCIe slot if your motherboard has one. If you have integrated graphics on your CPU, remove the GPU entirely and see if the system boots normally. If the system works fine without the GPU but fails with it installed, the card is almost certainly dead or dying. At this point, replacement is usually the only option.
What to Do If You Suspect GPU Failure
Recognizing the signs is only half the battle. Once you suspect your GPU is failing, you need to act quickly to protect your data and your system.
Back Up Everything Immediately
This is the most important step. A failing GPU can cause system instability that leads to data corruption. Copy your important files, photos, and documents to an external drive or cloud storage. Do not wait. Do it before you attempt any further troubleshooting.
Reduce the Load on the Card
Stop playing demanding games. Avoid video rendering or any GPU-intensive work. Lower the graphics settings in any application you must use. You can also use software like MSI Afterburner to manually reduce the GPU’s core clock speed and memory clock speed. This might stabilize the card temporarily and prevent crashes. It will hurt performance, but it could buy you some time.
Consider a Clean Driver Installation
As mentioned earlier, use DDU in Windows Safe Mode to remove all traces of the current driver. Then install the latest stable driver from the manufacturer. This eliminates software as the cause of your problems.
Monitor Temperatures and Clock Speeds
Use a tool like GPU-Z or HWMonitor to keep an eye on your GPU temperature and clock speeds. If you see temperatures exceeding the safe limit, or if the clock speed drops far below the base clock, you have a cooling or power issue. Cleaning the card and improving case airflow are your first steps.
When to Replace
If you have tried all the software fixes and cleaning steps, and the problems persist, the GPU hardware is failing. There is no reliable way to repair a failing GPU chip or VRAM at home. Professional repair services exist, but the cost often approaches the price of a new or used replacement card. In most cases, the practical solution is to purchase a new GPU. This is why many experts advise against buying a used GPU. The risk of inheriting someone else’s failing hardware is simply too high.
A failing GPU is a stressful event for any computer user. The good news is that by paying attention to these warning signs, you can often avoid total data loss and plan your next purchase without panic. Stay observant, keep your system clean, and act quickly when something seems off. Your computer will thank you.
